The 26-year-old joins the Uzbekistan Super League champions from FC Navbahor, adding to the head coach Pieter Huistra’s squad ahead of April’s group stage kick-off.
Turgunboev brings guile, experience and an eye for goal, with 110 Uzbekistan Super League appearances and 26 goals to his name, including one against Pakhtakor in September – one of seven in the 2020 campaign.
He has also featured for the Uzbekistan national team eight times, earning selection for the 2019 AFC Asian Cup, where he featured against Japan and Australia.
Turgunboev is Pakhtakor’s second official arrival within the last week, with 188-centimetre tall defender Marlen Chobanov also joining the club.
Huistra’s men are currently engaged in a training camp in Dubai, where an experimental line-up fell to a 3-0 defeat against Russian champions Zenit on Sunday, with the further matches to follow against Spartak Moscow and Latvian league winners FC Riga.
Pakhtakor were drawn alongside Sharjah and FC Tractor in Group B of the 2021 AFC Champions League on Wednesday, with either Al Wehda or Air Force Club to join them via the play-offs.
The Uzbek club reached the quarter-finals of the 2020 edition of the tournament, their best showing in Asia’s premier club competition since 2009.
